Original application yledllllarch 12 1915, Seria1jNo.=13,858... lDividedl and this application led February 13.

Be it known Ethat I,LARS W. BoDINsoN, a citizen of the United-States, and a resident, ofA-urora, in the county of- Kane, State of Illinois, vhavev invented certain new and useful Improvements in Deep-VVellPumps, of which the following is a-specification. ref# erence being had to the accompanying draw@ ings. l A

This invention relates t0 deep well pumps of the plunger. type, and it has for, its 'principal object the provision of-a construction and -arrangement', by reason of which Vthe pump rods and plungers may be readily drawn upward out of operativer position whenever desired for replacing "or repairing the plungers. It is'another objectof my inventionV to provide` such 'al ,construction in which one or more of the cylinders within which theY plungersroperate maybe raised to the surface with the-plungers without the removal ofthe wellcasing, ,this'result being attained preferablyv throughthe me,-v dium of the pump rods. It is still another object of my invention to' improve devices of this type in Vsundry details hereinafter pointed out. The preferred means by which I have accomplished my several objects are illustrated lin the accompanying drawings and are hereinafter specifically described. That which I believe to be new and desire to cover by this application'is setforth in the claims.

In the drawings: Figure lY is a central' Yvertical 'sectional view of the upperpart of the VVpumping mechanism located at the bottom ofthe well; Fig. 2 `is a continuation downward of the view yof Fig. 1; and l Y Fig. 3 is a continuation downward ofthe viewvof Fig. 2. v ,l Referring to the several figures 'of the 1917. -seriainaiiisgsziauV y.

anysuitable operating means, such operat- ,ing means being preferably of the general typeshown and claimed by Letters Patent ofthe UnitedStates, No. 1,124,295, issued on January 12, 1915, to The American Well Works, as the `assignee of Matthew T. Chapman. By the use of the mechanism of this patent, the upward stroke 0f, each pump rod will be caused to begin before the other pump rod reaches yits uppermost position.

1- rlhe constructionof the pumping mechanism comprising the subject-matter of this mechanism'shown and claimed in my application, Serial No. 13,868,l led March 12, i915, of which prior application the present application is a division. This 'mechanism comprises an upper cylinder 18 having plunapplication 'is along the general line of the gers 14-15'slidably mounted therein, and i A alower cylinder 16 -having plungers 17 and 18 slidably mounted therein. In the construction shown, the plungers 14 and 18 are `adapted to be reciprocated in unison by means of the pump rodV 11, .while the plungers 15 and 17 are'reciprocated in unison by the tubular pump rod 10. The plungers 14 and l15 coperate to force water upward from thecylinder 13 through'the well tube 12, while the plungers 17 and 18 coperate for forcing water upward through the well tube 12 from the cylinder 16.

. The means for connecting the plungers 14 and 18 with the pump rod 1-1 and the plungers 15 and 17 with the pump rod 10 comprises a cross-head 19 in the form of a spider secured by means ofV acoupling device 20 upon ythe lower end of the pump rod 11. The cross-head or spider 1-9 has fixedly connected with it a pipe or cylinder 21 extending downwardv about.v av pump rod 22 lalso secured to the cross-head 19, the pipe or vcylin der 21 being spaced away from the pump rod 22. A pipe 23 extends upward throughV the lower end'of the pipe orV cylinder 21, such pipe 23being connected as hereinafter described withthe pump rod 10. The lower end of the cylinder 21 is closed about the pipe 28 kby means of a coupling device 24 provided with a stuffing-box '25 of any suitable type. The coupling 24 is connected at its lower end portion with a sleeve 26 forming the inner shell portion of the plunger 14. A A valve` 27 is slidably-mounted upon the sleeve portionl26fof the plunger, being l-idapted to have its upward movement limited by the lower end portion of the coupling 24. klrlfheplunger 14 comprises radiilly-extending webs 28 by' which the vinner and outer shells of the plunger are connected, and comprises further suitablepacking' 29 secured upon theouterface of the ,outerYA shell.- 'By the construction herev described,

the plunger 14 is connected with `the pump rod 11 so as to be reciprocated therewith.

The upper end of the pipe 23 has tixedly mountedV thereon la 'coupling 30 in thel Jform of a spider and providedat its upper end' portion `witha.cross-head 31. This crosshead isconnected vby means ot boltsi32witl1 a cross-head '33 iiXedly connected withy the lower endet jthepumpl'rod 10. The'bolts 32,*preferablyA pass" through'- sui-table openingsnin. theiradially-extending arms ofi the cross-head 19, but this is' not. essential. As will'be readily understood, the arrangement of the parts is suchthat the cross-heads 31 and 33 areadaptedto befreciprocated vertically: with the pum-p*rod-'10v without interferencefwith -the normal verticalv reciprocat'ion of the cross-head 19 and theY pump rod 11.` ,The pipe 23 is connected at its lower end with the inner yshell porti'on'34 of. the

plunger/15,: a similar 'pipe' 35 being connectedv with-'the lower end of the portion 34 and 'extending downward therefrom. lThe plunger 15 is provided witha suitable valve 36' slidablymounted upon-the' inner shell portion 34, the valve being limited in'its upward movement vby 1a suitablesle'eve 37. rhe plunger lconiprises radi-'ally-extend` ing webs 38 which join the inner and outer shellportions, the outer shell'portion being provided with packingy 39 of' any 'suitable type. 'f l i The'well tube12 is" provided at its lower end with a coupling device by which it is l connectedwith the upper end of the cylin? der 16. :This coupling device comprises 'a sleeve' 40E mounted upon the well tube 12;y a sleeve 41'inountedupon the cylinder 16. and a plurality. of webs 42 which holdu the sleeves I40 and' 41in spaced relation to each other. The lowerend of the cylinder 13 is provided:withaclosure member 43 comprising inner. andjouter shell membersv spaced relative-to each otherby means lor' webs 44.

11 The: clos-ure memberV 43.' tapers' toward lgiyereiid,'fhavinga':snugitit within a corre,-` spo'ndingly L,shaped f seat provided' by the sleeves v40.-:#4-1y dt the ct'niplingr device' above describezl.:l Theclosurel member 43 is' pro- "r1 vided `with an' upwardly-opening valve 450i,"

any .suitable typjeyand is also provided with packing; 46,1 adjacent'. tolthe sleeve 41 and withfpacliingjll? adjacent to" the pipe 35 which` hasa The lower endli'o-f the pipe 35* within the working lit 'in the closure meml "cylinder 16 vis. provided with av coupling device 48 which connects the lower end of said pipe with a sleeve 49 which comprisesV the inner shell member of the plunger 17. The coupling'48` is inthe form of a cage, serving to.,.leave the lower end of the open into the interior of the cylinder 16. By `aninspection of the drawings, it will be seen that the cylinder 16 is thus in vvcoinmunication through the pipes 35`rv and 23, the

. coupling30, the pipe or cylinder 21, and the cross-head or spider 19 Withthe well tube 12 above the uppermost'v plunger. The plun* v ger 1'7"isi-provided with suitable packing 50 between its. inner shell member 49 and the pumpv rodsection 22; 'This plunger is also provided with a suitable upwardlyeopenin'g valfve 51 whose upwardV movement isli'mited by' theco'upling 48. The plu-nger comprises further"V radially-extending webs' 52 joining the inner and outer shell portions, the outer vshell portion being provided with packing of any suitable typein Contact with the inner fac'efof'tlie cylinder 16.

- YThe lower end of the pump rod 22 is secured byimeans of screwV threads-in the upper end of a sleeve 54 comprising the inner Vshell member of the plunger1'8,a lock-nut 55 being employed for securingi the plui'iger against-workingloose on said rod. rlClie plunger 18 comprises radially'-extending webs 56 Joining the limer and outer shell members, 'and the outer shell member is provided with suitable packing 5'7 in contact with the inner face' ofv the cylinder 16.

suitable upwardly-opening valve 58 is propipe 35 Y vided, limited in its upward movement by a Y -As will 'be readily understood, whenzthe 'iadmitted from the wellthrough the closure member 43. This water is forced upward through the wellv tube 12", through the alternatelyopening and closing valves 3f`and27, this result' being attained independentlyof the valve 45. At the same time water i's'be; f-

ing forced 'upward from' the cylinder Q16' by the coperation of the cylinders 17 and 18.` Such water is admitted through the up!` \\fard'lvopening valve 60 and passes'upward valves 58 vand. '751. passing upward through the coupling .48, the pipe 35,'the pipe23, the coupling 30, the pipe 214, and the' spider 19 Ithrough the alternately opening and closing cylinder,

intothe well tube 12 Vabove the plunger lai. This result is attained independently of the valve 60.

Whenever it is desired for any reason to lift the pumping apparatus upward out of position in the well, this. can be accomplished by drawing the pump rods l() and l1 upward. By reason of the connection of the various plungers with the pump rods l0 and 11, such plungers will move upward immediately inresponse to an upward pull upon the pump rods. When the plunger 17 comprising in the construction shown the coupling member 48, comes into contact with the closure-member 43, such closure-,member 4and' the cylinder 13 carried thereby are lwater upward through said well-pipe, and
